My iPhone 4s turned itself off and won't turn back on. What do I do?

My iPhone 4s turned itself off and won't turn back on. What do I do?

Thanks for your help. I tried plugging it in but nothing happened, I actually still had battery power left. I was able to solve my problem by holding down the power and home buttons, which reset the phone and got it started again.
Thanks for trying

    If you hold the home button and power button for about 10 seconds it will turn back on. I have had his issue 3 times but don't know what fixes it for good

    My iPhone 5c has turned itself off and won't turn back on, any ideas anyone?

    Hey Jswalker1969,
    Thanks for the question. If your iPhone is not powering on, see the following troubleshooting steps:
    Will not turn on, will not turn on unless connected to power, or unexpected power off
    1. Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
    2. Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion.
    Learn about LCIs and corrosion.
    3. Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
    4. After at least 30 minutes, if:
                   - The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen. Then unplug the phone from power. If it immediately turns off, seek service.
                   - The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
                   - Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
    5. If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
                   - If the display turns on, go to step 4.
                   - If the display remains black, go to next step.
    6. Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
    7. If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
    My issue is still not resolved. What do I do next?
    Contact Apple Support.

    Hello untech,
    I see that it has been awhile since you have posted with us on the HP Forums.  Please let me take a moment to say "Welcome Back". 
    I see that you are having an issue with the printer shutting it self off and not powering back on. 
    By chance do you have the printer power cable connected to a power bar/strip?  If so, please try connecting the printers power cable directly to a wall outlet.  Here is a document that explains the Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector.
    The printer in the document is a LaserJet printer but this document is meant for HP products in general and only uses the LaserJet as an example.
    I am also going to include a document for when The HP Printer Won't Turn On or Respond When the Power Button is Pressed.
    If by chance the issue is not resolved after doing the steps outlined,  I would then suggest calling HP's Technical Support to see about further options for you. If you are calling within North America, the number is 1-800-474-6836 and for all other regions, click here: click here.
    Please feel free to write me back if you have any other questions.
    I hope you have a great Monday.

  • IPhone 4S Shut itself off and won't turn on

    my iphone 4s has turned off and won't turn on.
    it doesn't respond to the power button and won't respond to being plugged in.
    the last time I used it was about an hour before I noticed it.
    the last thing I did was put one photo on to my photostream.
    it had been sitting in an air conditioning room, and on a desk during the whole hour or so I wasn't using it.
    anyone have any ideas what might be wrong with it?
    i am 100% sure I'll have to take it to a store to figure it out unless it suddenly works.. but any ideas would be helpful....

    My 4s did the same thing yesterday. I locked the screen, then about ten minutes later I went to use it and nothing would work. Like the phone was completely dead. I tried everything, plugging it in, reboot, nothing at all worked. Then about five minutes later I hit the lock button again and the apple logo appeared and it started rebooting. Not sure what happened!!

  • Iphone 5c turns itself off and won't turn on until plugged in

    I just received my replacement iPhone 5c and it worked fine the first night, the next day, the phone turned itself off, and would not let me turn it back on. I tried the reset option by holding down the lock and the home buttons, but that did not work. my phone only turns on when it is plugged in. It then shows me that battery is lows, and then powers on ad says 100% charged.
    My lower screen blinks while it is plugged in as well.....
    Any help?

    You might have a bad battery. But first try recalibrating the battery gauge. Run the battery all the way down until the phone shuts off and doesn't restart. Then charge for 4 hours with the wall charger. Repeat the process. If the problem remains you need a new battery.

  • IPhone 5C - Turned itself off and won't come back on.

    I have owned this phone since the day it came out (20th September) and it was fine up until a few weeks ago. It decided - frequently - to reboot itself, lines would appear on my screen and the brightness would decrease until the phone turned itself off. Soon the apple logo would appear and everything would be fine. I noticed that it would do this while I was on it while it was charging or when a lot of apps were open. I avoided doing these things, but it still would happen. Sometimes it would do it and the apple logo would not appear - I learned of the holding down the home and sleep/wake button at the same time hack, and would do that to get it back on. As time went on the problem would persist, sometimes it would take a few attempts to get the phone back on - I removed some recent apps and the phone was fine for about a week.
    Last Friday the phone did it again, so I decided to factory reset/restore through iTunes and then restore my backup. For a couple of days the phone was fine, up until last night where the phone switched off - thinking this was like all the other times I did what I'd usually do. But nothing, I've left it to charge, I've attempted to restore it. When I go to restore it the apple logo appears and the process bar appears, however iTunes turns around and says that it cannot restore the phone.
    I went onto here to try and attempt to have it sent back for service, I put in my IMEI number, and it said that I need to turn "Find my iPhone" off, I did that and now it says that it's still on, when it isn't!
    Does anyone know what I can do? Or shall I just ring them and figure out how to send it back through that?

    This happened to me yesterday. This probably isn't any use to you now, but for others with this question. This morning I took the back off of my phone, and I took the battery out and plugged it in to my laptop. It immediately lit up. We put the battery back in and restored it and it works better than ever. Not sure if this will work for all, but it worked for me!

  • Hi there my iPhone 4 has started to turn itself off and won't turn back on until it's charging

    As the title states.
    Suddenly my I phone 4 has decided it just wants to turn off and only comes back on occasionally. It is fully charged but says its empty, but not all the time. When it's plugged in its ok.
    Please help as I have no contact to anyone.
    Thanks

    You can either have Apple do it at the store, or you can find a repair shop local to you that does it.   If your phone is out of warranty, you'll save money going the local route.
    Call up and ask for prices.   I have no idea where you live or what country you're in.
    on the iPhone 4, it is VERY easy to change the battery if you have any mechanical skills.   Takes about 10 minutes.   Videos on youtube.

  • My ipad has turned itself off and won't come back on or charge.

    My ipad was on last night but when I went to use it this morning it was off and will not come on or charge.

    Try reset iPad
    Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears

  • My iPhone 5 has suddenly turned itself off and won't turn back on again. My lock button is also broke so holding the lock and home but together doesn't work. Any ideas? i'm desperate

    i can't get it to work, the screen is totally black and i've tried everything including charging, nothing is working

    Take the device to Apple for evaluation and likely replacement as there is obviously a hardware issue.
    I'm always amazed that people will leave with malfunctioning devices.

  • My iPod turned itself off and won't come back on now.

    My IPod Turned Off By Itself & Now It's Not Wanting To Turn On.

    Try:

    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - Try another cable                                                       
    - Try on another computer                                                       
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • My iPhone turned itself off and won't come on or charge, after I already restarted it once

    My iPhone 5s has turned itself off and won't come on or charge again I have already restarted it by holding the on/off switch and home button and it come back on and was working fine, but after an couple of hours it's turned itself back off again!! And won't let me restart it again. I don't know what's caused it as it was working fine yesterday and I hadn't dropped it or gotten it wet, what else can I do??

    A phone that is turned off wont receive calls. You could try to do a couple things: plug it in (even though it is fully charged), press and hold the power button down extra hard. Press and hold the power AND home buttons extra hard. Take it to the apple store.
